About the Airtac SAI100 Standard Air Cylinder SAI100BX350
The AirTAC SAI100X350 is a double-acting ISO 15552 profile cylinder engineered to deliver 3927 N of push force at 0.5 MPa. Its 350 mm stroke provides substantial linear travel for heavy-duty machinery. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in challenging environments. It utilizes PT tapered port threads and lacks a magnet, meaning it is optimized for pure actuation rather than direct sensor integration.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX350 Is Used
Heavy Stamping
Provides the robust linear force required for pressing and stamping rigid metal components in automated fabrication lines.
Bulk Material Diversion
Actuates large heavy-duty diverter gates on high-capacity conveyor systems handling aggregate or mining materials.
Large Clamp Actuation
Drives substantial clamping arms holding oversized workpieces securely in place during heavy machining operations.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX350 the Right Cylinder?
Delivering 3927 N at 0.5 MPa, this 100 mm bore is a robust choice for high-force tasks. If your application requires less force, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa, while moving up to the 125 mm bore provides 6136 N. The G1/2 port and M20x1.5 rod thread are standard for this bore size.
At 350 mm of travel, the extended rod is susceptible to bending under side loads. To prevent premature wear on the rod bearing, implement an external guide rail or use a guided cylinder variant. Remember that standard air cushions only decelerate the piston near stroke end; if the load must be held securely without continuous air pressure, utilize the SAIL locking variant or an external rod lock.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
